getQueryParam in Adobe Experience Platform Launch

Hi there,

In DTM, we were to use one or more of the following functions to grab the query string parameter (e.g. "eid") through JavaScript code:

_satellite.getQueryParam("eid")

s.Util.getQueryParam("eid")

Launch doesn't seem to support getQueryParam.

Without using Data Elements, do you know if Launch has a built-in function to retrieve query string parameters?

Thanks.
